Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If single-point detection method is used, then device complexity is reduced, but measurement precision and detection accuracy deteriorate
Solution Approach 1:
The detection system is segmented into multiple independent detector units arranged in an array along the width direction of the electrode plate. Each detector unit independently measures the transmitted ray intensity at its specific position, enabling parallel detection of surface density across multiple width positions simultaneously. This segmentation approach resolves the contradiction by maintaining relatively simple individual detector units while achieving high measurement precision through multi-point concurrent detection.
2Productivity
If single-point detection is used, then device complexity is reduced, but productivity and sampling rate worsen
Solution Approach 1:
The detector array segments the detection function across multiple parallel detector units, enabling simultaneous measurement at numerous width positions. This parallel architecture dramatically increases the sampling rate and productivity without requiring complex mechanical scanning mechanisms, as all detectors operate concurrently to capture the two-dimensional surface density distribution.
Solution Approach 2:
The detection system transitions from one-dimensional single-point detection to two-dimensional surface density mapping by arranging detector units along the width direction. This dimensional expansion enables comprehensive coverage of the electrode plate surface, simultaneously providing high-resolution spatial distribution data across both width and length directions, thereby大幅提升 productivity and sampling efficiency.
3Measurement precision
If ray scanning along length direction is implemented, then measurement precision of two-dimensional distribution is improved, but loss of time increases
Solution Approach 1:
The detection system maintains continuous measurement capability by having the ray beam continuously scan along the length direction while the electrode plate moves through the detection zone. The detector array continuously records transmitted intensity data at all width positions simultaneously, ensuring uninterrupted acquisition of two-dimensional surface density distribution without periodic interruptions or sequential scanning delays.
Solution Approach 2:
The continuous scanning process is segmented into multiple parallel detection channels, one for each detector unit along the width direction. Each channel independently and continuously measures surface density at its specific width position while the plate moves, allowing simultaneous progress along the length direction. This segmented parallel approach achieves high-resolution two-dimensional mapping without time loss, as all width positions are measured concurrently during the single pass through the detector.
